Hello, new to this. I just purchased my first land Rover lr2 2009. I got a roaring sound coming from the rear, when I let off of the gas, but stops when I press the gas, What could this be?

 

Possibly the rear differential failing.

 

The rear diff usually fails by 85K miles, if it fails at all. How many miles on this vehicle?

 

Rear diff needs a rebuild with upgraded kit.

 

The failure starts with a whine, but can be driven for a long time after that. 10K miles in my case, only got a little worse before we replaced it. so it could maybe get north of 100K before actual failure, presumably making more noise over time.

Did you use a rebuild kit, like this one? DIY or a local transmission shop?
